Dead Man Walking is my first successful 7DRL. The core game concept is managing two separate health pools: hit points and willpower. Hit points can be restored through a variety of means, while willpower cannot be regained under any circumstances. Losing all of your willpower results in an untimely loss.
The game was built in a coffebreak format and should not take more than 10 to 20 minutes to complete. It is also meant to be relatively easy to get into (compared to @Star Wars) and features tier-less weapons, straightforward damage, and simple but potentially deadly enemies. Last but not least, I spent a fair amount of time working on bosses and they should present interesting challenges.
You can download the game (windows only) and also read a more in-depth postmortem on my blog:

As previously mentioned, Dead Man Walking is a successful 7DRL and I'll leave the 7DRL version up for the foreseeable future on my blog. However, I'm planning on working on it some more, both in terms of horizontal content and vertical content (i.e., new content without increasing the length of the game and possibly some new floors as well). Beyond that, I have immediate plans to release a balance & polish patch later this week.
Technical details: the game was built off of the @Star Wars 0.7a trunk source and is, subsequently, written with Python 2.7 and the Doryen Library (libtcod).
